What is Incoloy?

Nickel-iron-chromium alloys bridging stainless and high-nickel grades for carburization, oxidation and selected acid services.

Typical applications

  • Furnace and heat-exchanger tubing
  • Petrochemical reformer / process piping
  • Acid and chemical plant lines (825)
  • Power and industrial heating systems

Selection guidance

Use H/HT when creep is design-critical. Use 825 for reducing-acid corrosion. Do not free-substitute 800 for 825.

This specification covers Seamless Tubes of nickel and nickel alloys, as shown in Table 1, for use in condenser and heat-exchanger service.

(A) Maximum unless range or minimum is given. Where ellipses (...) appear in this table, there is no requirement and analysis for the element need not be determined or reported.

(B) Element shall be determined arithmetically by difference.

(A) Maximum unless range or minimum is given. Where ellipses (...) appear in this table, there is no requirement and analysis for the element need not be determined or reported.

(B) Element shall be determined arithmetically by difference.

(C) Alloy UNS N08811: Al + Ti, 0.85 − 1.20.

This specification covers outside diameter and average wall, or outside diameter and minimum wall tube.

The sizes covered by this specification are 3 in. (76.2 mm) and under in outside diameter with minimum wall thicknesses of 0.148 in. (3.76 mm) and under, and with average wall thicknesses of 0.165 in. (4.19 mm) and under.

Tube shall be furnished in the alloys and conditions as shown in Table 2. for small diameter and light wall tube (converter sizes), see Appendix X2.

(A) Alloy UNS N08800 is normally employed in service temperatures up to and including 1100°F (593°C). Alloys UNS N08810, UNS N08811, and UNS N08120 are normally employed in service temperatures above 1100°F (539°C) where resistance to creep and rupture is required, and it is annealed to develop controlled grain size for optimum properties in this temperature range.

The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
